As with any Hudson Reed product - we supply everything you need to install your new goods. All you need to do is find a plumber.
When a new radiator is installed sometimes you can get air bubbles within the system and this prevents the hot water from circulating properly. You should have received a 'bleed' key with you radiator. The bleed valve is located on the underside of the 'towel bar' towards the left hand side. All you need to do is open the valve slowly, preferably with a towl at the ready, and release all the air until water starts to drip out. Once the water starts to drip close the valve tightly and the radiator should slowly start heat up.
You can install it wherever you need your towels warm! As long as a closed loop system is readily avaible you're be set for a smooth installation.
A BTU is a British Thermal Unit and they're used to establish how much output you need to heat a specific volumetric.
Our traditional school house radiators are comprised of two elements. The white inner section is manufactured from mild steel and the outer chrome section is chrome plated brass.
